The primary analysis involves a comparison of the mean ASES scores between the two surgical treatment groups on an intention to treat basis. This analysis is a two sample independent t-test to assess whether there is a statistically significant difference between groups for the mean ASES scores at baseline and each follow-up appointment up to two years. Repeated measures ANOVAs will be used to determine the effect of surgery from baseline to two years post-surgery (i.e. pre-operatively, 3, 6, and 12, and 24 month follow-ups) on ASES scores for each group. The 5% significance level is employed. The underlying assumption for the ASES score data is that there is a normal distribution. If the sample distribution is determined to depart from normal, then a Wilcoxon rank sum test with Bonferroni correction will be performed. The secondary analysis involves a comparison of the secondary outcome measures between the two surgical treatment groups. The elbow strength findings will be analyzed for differences between the two groups at each time point up to 2 years. Repeated measures ANOVAs will be used to determine the effect of surgery from baseline to two years post-surgery (i.e. pre-operatively, 3, 6, and 12, and 24 month follow-ups) on ASES and elbow strength for each group. Nominal demographic data will be compared using the chi-squared test, while ordinal data will be compared using a t-test.
